Does the band Big Time Rush lip sink?

Answer 1

First, you are asking about "lip synch"-- that means moving one's lips but the song has already been recorded and is not sung live. Yes, sometimes they do lip synch, but only under certain circumstances: for example, during a TV series, songs are often pre-recorded because the singers are doing something else, like acting out the plot of the story. However, Big Time Rush does perform live concerts, and at their concerts they do not lip-synch.
